Abstract: A system (10) for managed pressure drilling, or for workover of a hydrocarbon well with a wellhead, the system comprising a floating structure that is located in a body of water (41). A method is also described for connecting up the system for managed pressure drilling or well workover. The floating structure comprises a drill floor (13) and a work deck (14) that is movably arranged in an essentially vertical direction in relation to the drill floor. The system further comprises a riser (28) and a slip joint (32) that is connected to the underside of the work floor and to the upper end of the riser such that the work deck can be moved relative to the riser. The riser extends from the slip joint down to a wellhead valve device (40) arranged on the wellhead of the hydrocarbon well. The floating arrangement also comprises heave-compensated riser tensioners (17) which are connected to the slip joint such that the riser is held under tension.

Abstract: A floating structure 1, for instance a semi submersible platform, comprises a deck structure 2, vertical columns 3 and a pontoon structure 4. The floating structure 1 is moored to the seabed with anchor lines 7. The floating structure is moored with taut line anchoring system, and the vertical stiffness in the anchoring system is approximately 20% of the water plane stiffness for the floating structure. The pontoon structure 4 comprises at least two levels of pontoons and the columns 3 are formed to give variable water plane stiffness.

Abstract: The invention relates to a floating structure 1, for instance a semi submersible platform, comprising a deck structure 2, vertical columns 3 and a pontoon structure 4. The floating structure 1 is moored to the seabed with anchor lines 7. The mooring of the floating structure is done with taut line anchoring system, where the vertical stiffness in the anchoring system is approximately 20% of the water plane stiffness for the floating structure. The invention also relates to a floating structure as described above where the pontoon structure 4 comprises at least two levels of pontoons and where the columns 3 are formed to give variable water plane stiffness.

Abstract: The invention relates to a floating platform (1) for offshore drilling or production of hydrocarbons, comprising a topsides (2) and a substructure (3) having a lower pontoon (4) and columns (5) connecting the pontoon (4) to the topsides (2). Heave motion (s1, s2) of the platform (1) causes a change in the metacentric height (GM) of the platform. To counteract this change in metacentric height, the columns (5) are so adapted that the moment of area inertia of the waterline area of the columns (5) decreases on downward heave motion (s1) and increases on upward heave motion (s2).

Abstract: A riser guide is for use on a floating offshore platform, the platform comprises a topsides and a substructure having a lower pontoon, and at least one riser extends from a subsea location to the topsides. A number of riser guides are located in a guide housing which is secured to the platform. Each riser guide comprises a support arm rotatably mounted in the guide housing. A roller for laterally guiding the riser is rotatably mounted in an end of the support arm. A vertically movable wedge which is used for lifting the guide housing is connected to the support arm. During lifting of the guide housing the wedge lifts the support arm and the roller to an inactive position. When installing the riser guides, the guide housing and the riser guides are placed around the riser at the topsides, and lowered down in place by lifting gear connected to the wedges.

Abstract: A riser guide system is for use on a floating offshore platform, the platform having a topside and a substructure having a lower pontoon, and at least one riser extends from a subsea location to the topsides. A permanent guide is secured to the pontoon, a primary guide is located in the permanent guide, a secondary guide is located in the primary guide, and riser guides are located in the secondary guide and face the riser. In a method for installing the riser guide system, both the primary guide, the secondary guide and the riser guides are placed around the riser at the topsides, and lowered down to the pontoon.

Abstract: A device for evaporation of liquefied natural gas (LNG) on board a vessel. The device includes a pipeline through which LNG flows. The outside of the pipeline may be brought in contact with a heating medium, for example seawater. The pipeline is immersed in the sea and is connected to the vessel. The pipeline is enclosed by a shell through which seawater is pumped by a pump, which is operated by a motor on board the vessel.

A vertically movable working deck can be inserted into the opening, and is provided with an attachment for a riser which extends from a well to the working deck. The working deck is suspended in the floating device by riser tensioners in order to maintain approximately constant tension in the riser during vertical movement of the floating device.
